IMPROVEMENT IN ROTARY CUTTER AND SHIELD FOR PLO WS.

Specification forming part of Letters Patent No- 196,160, dated October16, 1877; application filed July 13, 1877.

To all whom it may concern Be it known that 1, WM. H. MELLoN, of FernValley, in the county of Palo Alto and State of Iowa, have invented anew and useful Improvement in Rotary Gutter and Shield for Plows, ofwhich the following is a specification z Figure 1 is a side view of aplow-beam to which my improvement has been applied. Fig. 2 is a frontview of the same, the plow-beam being shown in cross-section through theline as a, Fig. 1.

Similar letters of reference indicate corre' sponding parts.

The object of this invention is to furnish an improved rotary cutter forplows which shall be so constructed that sand cannot get to and wear itsjoiuuial, which shall be provided with a device for bending down weeds,grass, stubble, 8w, so that they will be turned under and fully coveredby the furrow-slice, and which shall be simple in construction andconven- The invent-ion will first be described in connection with thedrawing, and then pointed out in the claim.

A represents a plow-beam, to which is se cured, by a bow and yoke, B G,and a wedge, D, the upper part of the standard E. The lower part of thestandard E is forked, and in the ends of its branches are formed holesto receive the bolt F, that passes through and serves as a journal forthe hub of the rotary or circular cutter G.

H are two conical caps, which inclose the hubs of the cutter G. The capshave holes in their outer or smaller ends to receive the bolt or journalF, and the edges of their inner or larger ends rest against the oppositesides of the cutter G.

By this construction the caps H keep the dirt away from the hub of thecutter G, 'and thus prevent it and its journal from being worn sorapidly.

In one side of the caps Gr are formed small to said shield, and itsother end is attached to the branch of the standard E. The spring Jallows the shield to yield to accommodate itself to uneven ground, andto pass over obstructions. The outer edge of the shield is bent down orflanged to press projecting weeds, grass, 850., down into the furrow, toinsure their being covered.

When the cutter G is not needed it may be detached by detaching the boltF, and the shield used without it.

To the upper end of the standard E is pivoted the forward end of the rodK, the rear end of which is pivoted to the lever L. The lower end of thelever L is pivoted to the rear part of the plow-beam A, in such aposition that its upper end may be reached and operated by the plowmanto raise the cutter Gr when it is desired to have the plow enter theground deeper.

The lever L is provided with a lever spring- WILLIAM H. MELLON.
